/*******************************************************************************
The original prototype was to develop an idea I had about using jump indices
in a TypedArray for quickly matching hostnames (or more generally strings)[1].
Once I had a working, un-optimized prototype, I realized I had ended up
with something formally named a "trie": <https://en.wikipedia.org/wiki/Trie>,
hence the name. I have no idea whether the implementation here or one
resembling it has been done elsewhere.
"HN" in HNTrieBuilder stands for "HostName", because the trie is specialized
to deal with matching hostnames -- which is a bit more complicated than
matching plain strings.
For example, `www.abc.com` is deemed matching `abc.com`, because the former
is a subdomain of the latter. The opposite is of course not true.

The resulting read-only tries created as a result of using hnTrieManager are
2017-11-02 20:49:11 +01:00
simply just typed arrays filled with integers. The matching algorithm is
just a matter of reading/comparing these integers, and further using them as
indices in the array as a way to move around in the trie.

/***************************************************************************
Before vacuuming, each cell is 3 entry-long:
- Jump index to descendant (if any)
- Jump index to sibling (if any)
- character code
All strings stored in the un-vacuumed trie are zero-terminated, and the
character zero does occupy a cell like any other character. Let's
use _ to represent character zero for sake of comments. The asterisk
will be used to highlight a node with a descendant.
Cases, before vacuuming:
abc.com, abc.org: 16 cells
*
_ -- a -- b -- c -- . -- c -- o -- m
_ -- a -- b -- c -- . -- o -- r -- g
abc.com, xyz.com: 12 cells
*
_ -- a -- b -- c -- . -- c -- o -- m
_ -- x -- y -- z
ab.com, b.com: 8 cells
*
_ -- a -- b -- . -- c -- o -- m
_
b.com, ab.com: 8 cells
*
_ -- b -- . -- c -- o -- m
_ -- a
Vacuuming is the process of merging sibling cells with no descendants.
Cells with descendants can't be merged.
Each time we arrive at the end of a horizontal branch (sibling jump
index is 0), we walk back to the nearest previous node with descendants,
and repeat the process. Since there is no index information on where to
come back, a stack is used to remember cells with descendants (descendant
jump index is non zero) encountered on the way
After vacuuming, each cell is 4+n entry-long:
- Jump index to descendant (if any)
- Jump index to sibling (if any)
- character code
- length of merged character code(s)
Cases, after vacuuming:
abc.com, abc.org: 2 cells
*
[abc.co]m
[abc.or]g
abc.com, xyz.com: 3 cells

It's possible for a character zero cell to have descendants.
It's not possible for a character zero cell to have next siblings.
This will have to be taken into account during both vacuuming and
matching.
Character zero cells with no descendant are discarded during vacuuming.
Character zero cells with a descendant, or character zero cells which
are a decendant are kept into the vacuumed trie.
A vacuumed trie is very efficient memory- and lookup-wise, but is also
read-only: no string can be added or removed. The read-only trie is
really just a self-sufficient array of integers, and can easily be
exported/imported as a JSON array. It is theoretically possible to
"decompile" a trie (vacuumed or not) into the set of strings originally
added to it (in the order they were added with the current
implementation), but so far I do not need this feature.
New vacuum output array format:
byte 0..2: offset to descendant
byte 3..5: offset to sibling
byte 6: first character
byte 7: number of extra characters
Offset & count values are little-endian.
2018-11-06 16:38:37 +01:00
4 + 4 + 1 + 1 = 10 bytes for one character, otherwise
4 + 4 + 1 + 1 + n = 10 + n bytes for one + n character(s)
